Wi-Fi ® sensing for child presence detection(CPD)

Overview

Wi-Fi sensing enables 
high flexibility of sensor location with high detection capability

ORIGIN™ WirelessAI & Murata

Wi-Fi sensing can be freely located in contrast to cameras. 
We can accurately detect breathing and slight movement of children. 

We can detect changes of environment by using real time sensing with combination TRM(WirelessAI™) Technology of Origin Wireless™ and Murata’s high reliability wireless module.

 

Strengths

  • Existing Wi-Fi system can be used.
  • Tiny motion and breathing can be detected
  • High flexibility of antenna position
  • Child under a blanket and on the floor can be detected
  • Both front seat and rear seat can be covered.
  • No calibration required

CPD System configuration

Block Diagram of Wi-Fi system

Two Wi-Fi modules are required to detect a child in the car. 
Existing Wi-Fi systems like in-vehicle infortainment(Car navigation) or telematic control unit can be used. 
Wi-Fi sensing system can be built only by installing Originwireless software in either Wi-Fi system
